With the global greenhouse effect, environmental pollution, energy shortages and other issues have become increasingly prominent, reduce the energy consumption of buildings, industry and other fields, improve survival of our environment has become an important task of the whole society. Through scientific and technological innovation, to improve the performance of thermal insulation materials, the development of new insulation materials, to solve the problem of energy shortage, building a conservation minded society is of great significance. Inorganic nanoporous super thermal insulation material as a kind of green environmental protection type thermal insulation material, the nano, vacuum technology, breaks through the traditional insulation material limitations, in the heat preservation heat insulation performance, fire resistance, sound insulation performance and stability of the system have achieved great breakthrough.
 

        Since 1986, our country began to promote the construction of energy-saving work, the market has emerged a series of thermal insulation materials. At present, traditional polystyrene board, plastic extruded board, polyurethane and rock wool board occupies a major market for insulation materials, and these materials are not sustainable materials. Production of polystyrene board, plastic extruded board, polyurethane raw materials are petroleum derivatives, we consume these non renewable resources produced the products cannot be degraded, and now these materials is applied in a large area to the wall, can imagine decades later, these buildings are dismantled will produce many white foam, the future city will be surrounded by the large number of "white pollution". The application of traditional organic materials has brought a lot of social problems, and most of them have a headache. Organic materials after the fire burns out quickly, can not be effective to fight the blaze, the 2009 CCTV building fire, the 2010 Shanghai "II.15 ',' teachers apartment massacre is a typical, we should learn from it, to avoid similar incidents from happening again.
 

        In order to solve the problem of fire organic materials, rock wool board is pushed to the building thermal insulation materials market. Production rock wool board need to consume a lot of resources, each producing a ton of rock wool board consumes about 0.6 tons of standard coal, accounted for almost the in use 40070 cycle about energy consumption, which is typical of robbing Peter to pay Paul. And the current domestic production of so-called rock wool board are slag wool, in the slag wool production and use of the process will not only consume a large amount of energy, pollution of the environment, but also on the human body caused serious harm. We are now using this series of materials, large amount of non renewable resource consumption, should be eliminated, and using a lot of units only immediate interests, in order to reduce the cost, is still a lot of use, in energy saving at the same time is making a large amounts of waste, pollution of the environment, the long-term development of society is very adverse, in the future to pay for them will our children and grandchildren. So, to carry out energy-saving environmental protection work, not only the immediate interests, trade-off, the selection of thermal insulation material should be in consideration of the high efficiency, fire prevention, environmental protection, sustainability, economy and durability of these aspects.
 

        Early in 1992, Americans HuntA.J. at the International Conference on engineering materials raises the concept of super adiabatic (super ofheat) tree material, think super thermal insulation material is a kind of under the given conditions, thermal conductivity below the "air thermal conductivity of thermal insulating materials, such materials should be with a large amount of nano pore, also known as nanoporous super thermal insulation material oSi02 molecular unique nano porous network structure can effectively prevent the heat transfer, at atmospheric pressure and room temperature thermal conductivity of about 0.015 ~ 0.003W/ (m-k), than the thermal conductivity of the still air rate 0.026W/ (m-k) is low, the thermal conductivity of solid materials with the lowest. This super thermal insulation material has certain compressive strength, maximum use temperature can reach 1 200 DEG C, high temperature decomposition without harmful gases released, belonging to the green environmental protection material, with high porosity, low density and very low acoustic velocity, low dielectric constant, high ratio surface area, transparency and excellent performance, in the field of thermotics, optics, acoustics, microelectronics, petrochemical, aerospace, energy saving building has a very broad application prospects and industrialization of this new material will in energy conservation and emission reduction in China play an important role.
 

        Compared with the traditional thermal insulation materials, nano porous super thermal insulation material has excellent thermal insulation properties, under normal temperature conditions, generally 5 to 8 times the traditional materials. And with the increase of temperature, due to nanoporous super thermal insulation material internal unique nano pore structure, the has a more stable thermal insulation effect and its resistance to high temperature and relative thermal stability is one of the characteristics is unmatched by other materials. When the temperature of 300 DEG C to 400 DEG C, or the temperature above, nanoporous super thermal insulation material insulation effect reached more than 10 times of that of the traditional materials, energy-saving effect is more obvious, can bring greater economic benefits.
